7 Claims.

The invention relates to applicators for applying various substances'such as cleaning fluids, shoe polish, etc.; the applicator cap also functioning as a closure for a container.

One of the objects of the invention is to provide an applicator cap in which the parts can be easily and inexpensively manufactured and assembled.

Another object of the invention is to provide 10 an applicator cap of this type in which there 15 may have an area almost as great as the crosssectional area of the cap itself.

Numerous other objects and advantages of the invention will be apparent to those skilled in the art from the following detailed description, when taken in connection with the accompanying drawing, in which,

Figure 1 is a vertical sectional view of a blank from which the outer shell of the applicator cap is formed.

Figure 2 is a vertical sectional view of the inner shell.

Figure 3 is a fragmentary vertical sectional view of the two shells assembled, ready to be secured together; and

Figure 4 is a vertical sectional view of the complete applicator cap; parts being shown in elevation.

Referring to the drawing in more detail, numeral l refers to a metal blank having an annular groove 2 formed in the top thereof. This blank is finally formed into the outer shell of the applicator cap.

Numeral 3 refers generally to the inner shell of the applicator cap, and is shown in Figure 2, before being assembled. The body of the inner shell is preferably substantially cylindrical, and has an outwardly extending flange 4 at its upper end. This flange, in the specific embodiment illustrated, terminates in an upwardly and inwardly curled bead 5.

The cylindrical body of the inner shell 3 is preferably provided with an annular groove 6, to assist in attaching an applicator. The applicator pad, referred to by numeral 1, may be of any desired material, and it will be noted that the pad spans the entire lower end of the inner shell and projects slightly thereover, so that it may be attached thereto by means of a spring clamping wire 8 in cooperation with the groove 6. Of course any other desired means (Cl. ill-67.4)

could be employed for securing the pad to the inner shell, and string could be employed in place of the spring wire clamp. It might also be mentioned that while the lower end of the inner shell is shown-as open, yet it could readily be formed with a closed end, if desired.

The skirt of the outer shell of the applicator cap is provided with screw threads 9, by which the cap is attached to a container, though it will of course be understood that any other desired attaching means may be substituted for the screw threads. The edge of the skirt, below the threads, is preferably provided with a wire edge I0, which is shown as out-turned, though obviously it could be inturned if preferred.

In the manufacture of this applicator cap the outer and inner shells are shaped from sheet metal into the forms shown in Figures 1 and 2, respectively. The inner shell is then seated within the outer shell, as shown in Figure 3, with the curled portion or bead 5 of the inner shell nesting in the groove 2 of the outer shell, thereby centering the parts and temporarily holding them together.

The assembled shells are now placed on a threading machine, and the threads 9 are rolled in the skirt of the outer shell, and the wire edge I is rolled at the same time. During this threading operation the metal of the outer shell is tightly bent or crimped inwardly about the curled portion or bead of the inner shell, as clearly shown in-Figure 4, whereby the outer shell which is to be screwed onto a container, and the inner shell which receives the applicator, are firmly and permanently secured together.

The applicator pad I is now attached to the inner shell by the means illustrated, or by any other desired means. This pad entirely spans the mouth of the cylindrical inner shell, and this cylindrical member may be of a diameter almost as great as that of the outer shell; 'it being only necessary to leave sufficient space between the two shells to receive the neck of a bottle or other container. Hence the applicator of the present invention may be of very considerable area. On the other hand, the cylindrical body of the inner shell may be of any chosen diameter, large or small, and therefore in accordance with the present invention the applicator may be of any desired size, within the limits of any particular cap size.

When the cap is screwed or otherwise attached to a bottle or other container, the neck of the container in cooperation with the flange 4, will form a tight seal for the contents of the container. If desired, an annular liner of any ordinary liner material, maybe inserted between the inner and outer shells, and rest against the flange 4.

While we have described in detail the preferred form of the invention, yet obviously it may be changed and modified in various respects without departing from the spirit of the invention, and

all such changes and modifications are intended to be included within the scope of the appended claims.

What we claim is:

1. An applicator cap including an outer shell, means on said outer shell for attaching it to a container, a hollow circular inner shell spaced inwardly from the outer shell, means for securing the two shells together, and an applicator attached to and spanning the lower end of the hollow inner shell.

2. An applicator cap including an outer shell, means on said outer shell for attaching it to a container, a hollow circular inner shell spaced inwardly from the outer shell, said hollow inner shell having its lower end open, means for securing the two shells together, and an applicator attached to and spanning the lower open end of v the inner shell.

3. An applicator cap including an outer shell, screw threads formed in the skirt of the outer shell, the skirt terminating in a wire edge, a hollow circular inner shell spaced inwardly from the outer shell, means for securing the two shells together, and an applicator attached to and spanning the lower end of the hollow inner shell.

4. An applicator cap including an outer shell, means on said outer shell for attaching it to a container, an annular groove formed in the outer shell; a hollow circular inner shell spaced from the outer shell, an annular curled portion on the inner shell, said annular curled portion fitting in said annular groove, the containerattaching means on the outer shell maintaining the annular curled portion and the annular groove in assembled relation, and an applicator attached to-and spanning the lower end of the hollow inner shell.

5. Anapplicator cap including an outer shell, means on said outer shell for attaching it to a container, an annular groove formed in the outer shell, a hollow circular inner shell, an outwardly extending flange at the top of the inner shell spacing the inner shell inwardly of the outer shell, an annular curled portion at the periphery of said flange, said annular curled portion fitting in said annular groove, the container-attaching means on the outer shell maintaining the annular curled portion and the annular groove in assembled relation, and an applicator attached to and spanning the lower end of the hollow inner shell.

6. An applicator cap including an outer shell, an annular groove formed in the outer shell, a hollow circular inner shell, an outwardly extending flange adjacent the top of the inner shell, an annular curled portion at the periphery of said flange, said annular curled portion fitting in said annular groove, screw threads formed in the outer shell for attaching it to a container, the formation of the screw threads causing the annular groove and the annular curled portion to be tightly clamped together, and an applicator attached to and spanning the lower end of the hollow inner shell.

'7. An applicator cap including an outer shell, an annular groove formed in the outer shell, a hollow circular inner shell, an outwardly extending flange adjacent the top of the inner shell, an annular curled portion at the periphery of said flange, said annular curled portion fitting in said annular groove, screw threads formed in the outer shell for attaching it to a container, the formation of the screw threads causing the annular groove and the annular curled portion to be tightly clamped together, an annular groove formed in the inner shell, an applicator mounted on and spanning the lower end of the hollow inner shell, said applicator projecting over the groove in the inner shell, and a spring wire clamp cooperating with the groove in the inner shell to clamp the applicator to the inner shell.
